Claims (10)

In the case of generating a composite image that has been subjected to exposure correction by performing image composition on a plurality of images, among the plurality of images obtained by a plurality of imaging operations, the image composition is performed based on information about these images. A selection unit for selecting an image to be used ;
Gain adjustment means for increasing the number of images selected by the selection unit by an insufficient number when the number of images selected by the selection unit is insufficient with respect to the number of images required for the image composition ; An image processing apparatus comprising:   The image processing apparatus according to claim 1, wherein the information about the image includes at least one of image contrast, color information, focus information at the time of image acquisition, and displacement information between images.   3. The selection unit according to claim 2, wherein when the difference in contrast between the reference image and other images among the plurality of images is equal to or greater than a predetermined value, the other images are not used for the image composition. The image processing apparatus according to 1.   3. The image processing according to claim 2, wherein the selection unit does not use, in the image synthesis, an image having a contrast having a difference equal to or greater than a predetermined value with respect to an average contrast value in the plurality of images. apparatus.   The image processing apparatus according to claim 2, wherein the selection unit does not use another image having a displacement amount greater than or equal to a predetermined value with respect to a reference image among the plurality of images for the image composition. .   The image processing apparatus according to claim 5, wherein the selection unit uses an image that minimizes a displacement amount with respect to another image as the reference image.   The image processing apparatus according to claim 1, wherein the image processing apparatus is an imaging apparatus including an imaging unit that performs an imaging operation.   The image processing apparatus according to claim 7, wherein the imaging unit acquires more images than the number of images necessary for the image synthesis by an imaging operation. In the case of generating a composite image that has been subjected to exposure correction by performing image composition on a plurality of images, among the plurality of images obtained by a plurality of imaging operations, the image composition is performed based on information about these images.
